Flynn’s Assassin by N.J. Walters

When mercenary and space trader Flynn Marks is approached by a woman in a seedy bar, he assumes she’s not just looking for a good time. He’s made enemies over the course of his life. With his family finally safe and settled, he’ll handle this latest threat on his own.
Cerena Phelps has been tasked with killing a man if she ever wants to see her teenage son again. While she’s no stranger to fights—being a woman bouncer is a tough job—she’s never killed a man.
Her plan? Lure Flynn away from the bar, seduce him, and kill him when his guard is down. Not a hardship given her unexpected and intense sexual attraction for her target. When her attempt on Flynn’s life fails, they must learn to trust each other if they both hope to survive and rescue her son.
